RIGGI, 49, who stabbed her three young children then tried to cover up their deaths with a gas explosion, will be treated at notorious Rampton hospital in Nottinghamshire.

MONSTER mum Theresa Riggi has been moved to a high-security ­psychiatric hospital in England.

Riggi, who was jailed for her killing her three children, is being treated at notorious Rampton hospital in Nottinghamshire.

And she is said to be enjoying her life of relative anonymity at the hospital, where fellow patients include “Angel of Death” child killer Beverley Allitt.

Soham murderer Ian Huntley has also been treated there. A source said: “Nobody knows her or what she is in for. She is left alone, whereas in Scotland she had been very high-profile and, ­therefore, a target.”

Riggi – who psychiatrists said suffered from ­narcissistic, paranoid and histrionic ­disorders – killed twins Austin and ­Gianluca, eight, and daughter, Cecilia, five, at a flat in Slateford, Edinburgh, in August 2010.

She used a different knife to kill each child, following a bitter marriage split from their dad Pasquale.

Riggi tried to cover up their deaths with a gas explosion at the flat, before leaping from a balcony.

The American was told to serve 16 years after pleading guilty to culpable homicide on the grounds of diminished responsibility.

The Record can reveal she was sent to Rampton, near Retford, several months ago because it was felt medics there were better placed to treat her.
